Kit

Kit (formerly ConvertKit) rebranded in late 2024 but the product is the same one creators have leaned on for years: a clean, opinionated email platform built around the idea that you’re running a creator business, not a corporate marketing campaign.

Who it’s for

Newsletter writers, course creators, podcasters, indie hackers selling digital products. Anyone whose business model is “build an audience, then sell to it.” Kit’s monetisation tools (paid newsletters, digital product sales, tip jars) make it especially useful if email is a revenue channel rather than just a comms channel.

If you’re running cold outbound or transactional email at scale, this isn’t the right tool. Look at Brevo or a sender like SendGrid.

What it actually does well

The free Newsletter plan is genuinely generous: 10,000 subscribers, unlimited emails, unlimited landing pages and forms. That’s enough headroom for most newsletters to validate before paying anything. The trade-off is just one automation and one sequence on free, which is the right gate to push serious users into Creator.

The visual automation builder is the other strength. Compared to MailerLite’s basic automations or Mailchimp’s clunky interface, Kit’s flow editor is fast to build in and easy to debug when something misfires.

Free migration on paid plans is a quietly important feature: if you’re on Substack or Mailchimp and want to switch, Kit’s team handles the import.

Where it gets awkward

Kit raised prices significantly in September 2025. The old $15/mo Creator plan is gone, replaced with a $29-39/mo entry point depending on your subscriber count and billing cycle. For solo creators with small lists, that’s a meaningful jump.

Pricing scales with subscriber count, which works fine until you have a 50K+ list and start looking at $300+/month. At that point it’s worth comparing seriously against ActiveCampaign or Klaviyo, both of which give you more depth at higher volumes.

How it compares

Versus Beehiiv: Beehiiv has aggressive newsletter-specific features (referral programs, ad network) but a smaller free tier. Kit feels more like a real email platform; Beehiiv feels more like a publishing platform.

Versus MailerLite: MailerLite is cheaper at every subscriber tier. Kit is more polished and has better creator-specific monetisation. Pick MailerLite if budget is tight, Kit if email is core to your business model.
